Heritability of the Symbiodinium community in vertically- and horizontally-transmitting broadcast spawning corals

Abstract The dinoflagellate-coral partnership influences the coral holobiont’s tolerance to thermal stress and bleaching. However, the comparative roles of host genetic versus environmental factors in determining the composition of this symbiosis are largely unknown. Here we quantify the heritabilit...
